Issue Type: Bug Affects Versions: 5.4.17 Assignee: Unassigned Components: hibernate-entitymanager Created: 22/Jul/2020 09:15 AM Environment: Spring Boot 2.3.1.RELEASE, Java 11 (Adopt OpenJDK), H2 DB & Postgresql 10, Windows 10 Priority: Major Reporter: Benjamin M. ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5f1862af1084620015f82ef2 )

I was trying to fetch an entities association and have that fully initialized (will be serialized to JSON):

SELECT u.groups FROM User u WHERE u.id = ?1

Applying a Named/Ad Hoc Fetch Graph yields an Exception. E.g. for this Graph:

EntityGraph<Group> eg = em.createEntityGraph(Group.class);
eg.addAttributeNodes("permissions");

I get:

> 
> 
> 
> org.hibernate.QueryException: query specified join fetching, but the owner
> of the fetched association was not present in the select list
> [FromElement{explicit,collection join,fetch join,fetch non-lazy
> properties,classAlias=u,role=com.example.assocFetchGraph.persistence.User.permissions,tableName=
> 
> 
> Unknown macro: {none}
> 
> 
> ,tableAlias=permission3_,origin=null,columns={,className=null}}]
> 
> 

That is because both classes have a `permissions` property.

Expected behavior would be, that the Fetch Graph's attributes would be resolved relative to Group, not User. (But the JPA spec doesn't seem to be very clear here).

I have created a reproducing example: https://github.com/cptwunderlich/assocEntityGraphMRE

We had a discussion about this on Zulip #hibernate-user "EntityGraph resolution"
I also created a StackOverflow question: https://stackoverflow.com/questions/63015923/jpa-select-association-and-use-namedentitygraph

I provde an excerpt of the code here for your convenience:

{{@Entity
public class User

{ @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @Enumerated(EnumType.STRING) @ElementCollection(targetClass = Permission.class) @CollectionTable(name = "USERS_PERMISSIONS", joinColumns = @JoinColumn(name = "uid")) private Set<Permission> permissions = EnumSet.of(Permission.FOO); @ManyToMany(fetch = FetchType.LAZY) private Set<Group> groups = new HashSet<>(); }

@Entity
@NamedEntityGraph(name = Group.ENTITY_GRAPH,
attributeNodes =

{ @NamedAttributeNode("permissions") }

)
public class Group

{ public static final String ENTITY_GRAPH = "group-with-permissions"; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @Enumerated(EnumType.STRING) @ElementCollection(targetClass = Permission.class) @CollectionTable( name = "GROUPS_PERMISSIONS", joinColumns = @JoinColumn(name = "gid") ) private Set<Permission> permissions = EnumSet.noneOf(Permission.class); }

// Query:
List res = em.createQuery("SELECT u.groups FROM User u WHERE u.id = ?1")
.setParameter(1, u.getId())
.setHint(GraphSemantic.FETCH.getJpaHintName(), em.getEntityGraph(Group.ENTITY_GRAPH))
.getResultList();}}

Stack Trace is:

The repository also contains a test case where I JOIN FETCH permissions and that works. Interestingly, in my actual code, I have and additional JOIN FETCH for a ManyToOne and I get the above Exception for that additional property.
